Title: Digital-analog converting method
Inventor: KUBO MITSUMASA
IPC: H03M1/66
Filed: 1986-02-28
Abstract: PURPOSE:To continue dither addition while it is prevented that a summing signal exceeds a maximum digit by lowering the level of dither when the level of data is increased in the high level range of data. CONSTITUTION:The presence of possibility of a sum C of outputs of a digital dither generator 3 in N-bit (N>M>=2) aud N-bit (N>=3) digital information signal A exceeding N-bit is decided by an overflow level discriminating circuit 5. When it is decided as the presence of possibility in excessof N-bit, the level of the digital dither 3 is limited (4) in the range not exceeding the N-bit. Then the digital information signal A and the data of a digital dither B are added (2), the result is converted (7) into an analog signal and the analog dither is subtracted (9) from the analog addition signal E.

Abstract: PURPOSE:To suppress a fault to the minimum even if the fault is generated in some control unit by supervising a use state of a common bus in each control unit, and suspending the use of the common bus forcibly in the case of the common bus is used continuously extending over a prescribed time. CONSTITUTION:In a multi-processor system, the time when each control unit 10 can use a common bus 3 is determined in advance, and a monitoring time set to a common bus supervisory circuit 14 is set longer than said time.
